An improved control system and method for an automatic/semi-automatic transmission system (10) including an automatic change gear transmission (12) driven by a throttle (26) controlled engine (14) is provided. The control system includes a processing unit (42) for receiving inputs indicating at least throttle position (THL) and vehicle speed (OS) and for determining vehicle acceleration (dOS/dt) and for processing these inputs in accordance with a program or logic rules to determine the selected engaged gear ratio and for issuing command signals to a transmission shifting mechanism (34). The processing unit includes logic rules by the control will execute skip upshifts upon sensing certain predetermined conditions. |
